Climate change and biodiversity are two completely different things. In some areas, climate change will increase biodiversity, allowing more species to live in certain climates, but it will make some species lose their habitats. Biodiversity helps ecosystems thrive, and generally keeps things in balance. However, introducing too many species in an area can cause increase competition for food, risking predators of different species to kill one another off.

Explanation: Cataract is the opasity or clouding of the lens of the eye making it to deviate from it's normal natural transparent/clear form.It is characterised by blurry vision.Treatment of cataract is by removal of the opaque cataract and replacing it with an clear artificial lens.
Cataract extraction and intraocular lens implant is a generally safe procedure,so when pain occurs after the procedure,it indicates that infection has set in or there is bleeding in the procedure site and it is advices that when a patient notices any of these,it should be reported immediately. Certain things should be avoided after cataract extraction and intraocular lens implant, things like soap,having a bath,washing the hair can all irritate the eye so all these should be avoided from few days to atleast 2weeks after the surgery.
When the patient that has undergone cataract extraction and intraocular lens implant experiences flashes of light,it indicates they there is retinal detachment,this is not expected, but if it is experienced by the patient,it should be reported immediately too.
As mentioned earlier, cataract extraction and intraocular lens implant is generally a safe procedure and rapid improvement in vision is always recorded in some people although some other patients stay several weeks before they achieve an improvement in visual acuity.
